Application filed January 18, 1905. Serial No. 241,641.

To all whom it may concern:

Be it known that I, ARTHUR KoPrEL, engineer, of Dorotheenstrasse 45,Berlin, Germany, have invented certain new and useful 5 Improvements inTrains of Wagons, ofwhich the following is a full, clear, and exactspecification.

My invention relates to trains of wagons of the type described in thespecification of Let- 1 ters Patent No. 776305, which comprises a traintwo-wheeled wagons, the body of each of which is rigidly mounted on itsaxle so as to form a rotary frame with large wheels, the wagons beingconnected in pairs to form com- I posite elements by means ofconnections creating a direct dependence of the positions of the axlesand the bodies joined thereto, while supporting members connecttrunnions on axles and bodies belonging to one composite 2 element.

The present invention consists in a development of that described in theabove-mentioned specification. The connecting member between thetrunnions on the axles of each pair of wagons is retained, but adifferent form of connection for the angular dependence between the twoaxles and bodies of or frames of each composite element isadoptednamely, the rear wagon or frame of each composite 3o elementconsidered relatively to the direction of travel is rigidly fixed bymeans of a bolt, pin, or the like to the member connecting the trunnionsof each pair. As described in the former specification, each compositeelement or pair is coupled to the next composite ele ment or pair byordinary pins or the like.

The accompanying drawings illustrate the invention diagrammatically,Figure 1 being an elevation, and Fig. 2 a plan. 4 In carrying out theinvention the axles a, provided with large wheels Z) and the bodies 0,rigidly mounted on the axles, thereby forming rotary frames, areconnected, as before, by members d to form composite elements or pairs.Pins g are used for coupling the composite elements to each other. Themember (Z, however, of each composite element is adapted to receive abolt, pin, or the like f, by which one of the wagon bodies or frames 5of the respective element may be rigidly se- The rear wagon or frame ofcured thereto.

each element or pair considered relatively to the direction of travel isthe one which is to be rigidly secured to its connecting member.

. It has been found in practice that this method of coupling practicallyfulfils all requirements both for turning curves and for returning tothe straight line again. The rear wagon need not accurately follow theforward wagon, which acts as a rotary frame, but may turn about asmaller radius. This, however, is equalized by the next coupledcomposite element, so that a correct track of the total wagons results.

A special advantage obtained by the above 5 method of coupling ascompared with other systems is that the train of wagons can be hauled ineither direction by withdrawing one set of the bolts f and inserting theother set, so as to lock the respective rear wagons ac- 7 cording to thedirection of travel. This permits travel over very sharp angles, themotor-wagon or traction-engine being taken from one end and coupled tothe other.

The possibility of turning small curves is indicated in the figures bythe semicircular turn-tables or guides dand the projecting breast-platesor supports it.

Having thus described my invention, what I claim as new, and desire tosecure by Letters 30 Patent, is-

1. The combination with a plurality of vehicles, of members forconnecting said vehicles together in pairs and means for connecting onevehicle of each pair rigidly to its con- 5 necting member.

2. The combination with a plurality of vehicles, of members forconnecting said vehihicles together in pairs and removable means forconnecting one vehicle of each pair rig- 9 idly to its connectingmember.

3. The combination with a plurality of vehicles, of members forconnecting said vehicles together in pairs and means for connecting therearmost vehicle of each pair rigidly to its connecting member.

4. A wagon train consisting of largewheeled rotary frames, each of saidframes consisting of one set of Wheels, and a loadingbody rigidlysecured thereto, a supporting I00 longitudinal connecting-piece lyingunderneath the bodies of two of the frames so as to In testimony whereof1 have signed my name to this specification in the presence of twosubscribing Witnesses.
